Danfoss frequency converter VLT® Refrigeration Drive FC 103 is designed to help drastically reduce the life cycle cost of refrigeration equipment. It can improve efficiency and reliability, provide integrated process control functions and a specially designed debugging environment to meet the needs of refrigeration applications. It also has installation guides that use common refrigeration terminology. Therefore, refrigeration technicians and installers can install and debug easily and safely.
    The continuous variable speed control of VLT Refrigeration Drive realizes intelligent capacity control. By balancing the capacity with the actual load to maintain stability, the performance coefficient of the entire device is improved, thereby achieving significant energy-saving effects in various applications.
The frequency converter contains all necessary modules that comply with EMC standards. The integrated adjustable radio frequency interference filter can reduce electromagnetic interference, and the built-in DC loop reactor can reduce harmonic distortion in the main power supply network. All these functions are integrated into the inverter at the factory, which can save cabinet space. Efficient EMC auxiliary devices also allow the use of cables with small cross-sections, reducing installation costs.
